ABSTRACT

A reconfigurable nest handling system for handling nests of objects arranged in a predetermined pattern is presented and applied to a system for filling nested pharmaceutical containers with a pharmaceutical fluid. In one general aspect, the system comprises a sterilizable chamber containing a planar rotary stage with tub and nest positioning systems that may be reconfigurable for holding differently sized pharmaceutical container tubs and nests and pharmaceutical closure tubs and nests. The chamber has a rotatable cover removal station, a rotatable filling station with a dispenser head, and camera guided vacuum pickup facilities for handling container and closure nests. The vacuum pickup facilities may be reconfigurable for handling differently sized nests. An associated method for filling the containers comprises establishing an aseptic condition within the chamber; removing covers from a container tub and a container closure tub by operating both the rotary stage and the cover removal station. The vacuum pickup facility transfers into the fiducial locating structure a container nest bearing pharmaceutical containers. The fluid is dispensed into the containers by operating both the rotary stage and the filling station. A container closure nest is placed on the container nest in the fiducial locating structure with closures in correspondence with containers. A ram in the chamber forces the closures into the containers.

BACKGROUND OF THE INVENTION Field of the Invention

This present invention relates to the medical field and moreparticularly to apparatus and associated methods for sterilization ofand sterile handling of pharmaceutical materials and containers forpharmaceuticals, including bringing pharmaceuticals into form foradministration to medical or veterinary patients. In one aspect, itrelates to the programmed and automatic operation of such apparatus.

Background

The subject of filling pharmaceuticals into pharmaceutical containers isa major aspect of the Pharmaceuticals Industry. The subject is heavilycontrolled by various governmental and official bodies in variouscountries. Technologically, the subject is a challenge in that thepharmaceutical products need to be filled into the containers under verystrict aseptic conditions. Very specific procedures are specified forthis task to a degree that makes the handling of pharmaceuticalsprofoundly different from the handling of any other industrial product,including specifically semiconductors, which also demand extreme andconsistent environmental conditions. Indeed, the parallels between thehandling of semiconductors in semiconductor “clean laboratories” and thehandling of pharmaceuticals in aseptic isolators are superficial. Theyshare the use of such “clean laboratories”, but there is no inherentaseptic requirement associated with semiconductor manufacture.

The filling of pharmaceutical containers with fluid pharmaceuticalsspecifically requires the aseptic handling of both the containers andthe fluid pharmaceutical itself. This leads to complex mechanisms andprocedures, many of which may be automated to one degree or another.Often, the production equipment for fluid pharmaceutical handling isbulky and expensive. This creates a problem for smaller operations,particularly in the small-scale production and development environments.As the field has developed, the need for smaller, more compactequipment, particularly in the filling and compounding of fluidpharmaceuticals, has become evident.

The prior art is typically characterized by the use of vibratory bowlsand escapements. Many prior art systems also employ gloves for use bythe operator to access the interior of the chamber.

DETAILED DESCRIPTION

The embodiments disclosed below are illustrative and not intended to beexhaustive or limit the invention to the precise form disclosed in thefollowing detailed description. Rather, the embodiments are chosen anddescribed so that others skilled in the art may utilize their teachings.

The present invention relates to an apparatus and method for filingpharmaceutical containers with a pharmaceutical fluid substance in aspatially constrained environment. In FIG. 1A, a filling system 1000comprises a sealable chamber 100 in communication with an ambientenvironment, the sealable chamber 100 being capable of having an asepticenvironment established within its interior and capable of maintainingthat aseptic environment within its interior. The interior of sealablechamber 100 may be rendered aseptic by any one or more of a number oftreatments, including but not limited to treatment with a sterilant,such as steam, hydrogen peroxide vapor, ozone, nitrogen dioxide, andethylene oxide. The structures and mechanisms to perform suchsterilization steps are well known in the art and are not shown in FIG.1A.

Chambers 200 and 300 are separated from chamber 100 by upper wall 110and lower wall 120 respectively and are not required to be capable ofmaintaining aseptic environments within their interiors. Thecommunication of chamber 100 with the ambient environment may be via asuitable aseptically sealable access door 102, schematically shown inbroken outline in FIG. 1A. Suitable sealable doors and ports are wellknown in the art and will not be dwelt upon further in thisspecification. The ambient environment may be, for example, a clean roomadapted for the handling of pharmaceuticals during production. Sincespace is at a premium in such spatially constrained clean environments,there is much merit in reducing the so-called “footprint” of equipmentto be housed in the clean environment.

The terms “aseptic” and “sterilize” and their derivatives are to beunderstood as follows for the purposes of the present specification.Establishing an aseptic condition in the interior of a chamber shall beunderstood to mean establishing that condition throughout the internalatmosphere of the chamber as well as on substantially all exposedinterior surfaces of the chamber. This shall include the surfaces of allitems, containers, subsystems and the like exposed to the interioratmosphere of the chamber. To the extent that extremely tight crevicesor microscopic crevices may exist in the interior of the chamber suchthat a sterilizing gas or vapor may not perfectly penetrate into suchtight regions, for example, the degree of sterilization in practicalcases may not be total. This is acknowledged in both the industry and inthe standards set for the industry. The action of establishing anaseptic condition within the interior of the chamber and “sterilizingthe interior of the chamber” shall have the same meaning in thisspecification.

Introducing into the interior of a chamber with an aseptic condition anitem of which the surfaces are not suitably sterilized destroys theexisting aseptic condition within the chamber. Conversely, introducingan aseptic or sterilized item into an interior of a chamber that doesnot have an aseptic condition within that interior does not render thatinterior aseptic. In fact, all it does is to destroy the asepticcondition of the surface of the item so introduced. Similarly,introducing filtered air, even with all biological entities filteredout, into an unsterilized chamber does not in any way sterilize thechamber or render it aseptic to a degree acceptable in thepharmaceutical industry. The reason is that the interior surfaces of thechamber are not sterilized by the introduction of such air. All that isachieved is to contaminate the filtered air with active biologicalspecies resident on the interior surfaces of the unsterilized chamber.

In the interest of clarity and completeness, it should also be recordedthat in the art the term “aseptic” is also sometimes used in associationwith the introduction of pharmaceutical fluids along aseptic tubes intobodies within controlled chambers. In such cases the term in the artrefers to the condition inside the tube or to the fact that thepharmaceutical fluid may be filtered to a suitable degree. This in noway sterilizes or renders aseptic the interior of the chamber inquestion. The aseptic condition in such cases is confined to theinterior of the tube bearing the pharmaceutical stream. Such streams areoften filtered to a high degree, but such filtering affects only theinterior of the particular tube and does not in any way sterilize theinterior of the chamber.

In some prior art systems, containers introduced into a chamber for thepurposes of being filled with a pharmaceutical are routed throughsterilizing subsystems. This kills biological species on the containers.When such sterilized containers are introduced into the chamber when thechamber itself is not aseptic the containers lose their asepticcondition as biological species contained within the chamber willdeposit on the previously aseptic containers.

It should also be pointed out that pharmaceutical or semiconductor cleanrooms of any quality level, including “Class 100”, “Class 10” or “Class1”, even when employing laminar flow hoods and the like or any qualityof HEPA (High Efficiency Particulate Air) filters or ULPA (Ultra LowParticulate Air) filters, cannot constitute an aseptic chamber becausethey do not have an assurable means to render the surfaces of the roomsterile or aseptic. Standards for clean rooms exist from both the UnitedStates Federal Government and ISO (International StandardsOrganization). These specify in great detail to different standards theallowed particulate content of a cubic volume of air in such a cleanroom facility. None of these standards address the matter of biologicalspecies present on surfaces in the room. This serves to make the pointthat a chamber cannot be rendered aseptic by the management of itsatmosphere or airflow only. Nor, conversely, can the chamber be renderedaseptic by the sterilization of only the surfaces of its interior.

The text “Guideline for Disinfection and Sterilization in healthcareFacilities, 2008” by Rutala et al from the Center for Disease Controllists a compendium of mechanisms and methods for sterilization. Ourconcern in this specification is specifically with those mechanisms forsterilizing the interior of a chamber; that is, sterilizing both theinterior surfaces and the atmosphere within the chamber. Given therequirements, vapor base methods are most appropriate to the task. Theseinclude, but are not limited to, treatment with heated water vapor,hydrogen peroxide vapor, ozone, nitrogen dioxide, ethylene oxide,glutaraldehyde vapor or other suitable sterilizing gases and vapors. Inone suitable method appropriate to the present invention, thesterilization is by means of hydrogen peroxide vapor which is thenflushed using ozone before the chamber is employed in the filling ofpharmaceutical containers.

The subsystems of the apparatus 1000 contained with sealable chamber 100will now be described at the hand of FIG. 1A to FIG. 1G. Due to thecompactness and density of components and subsystems of apparatus 1000,certain components and subsystems are omitted from the drawings of FIG.1B to FIG. 1G in the interest of clarity and the focus is placed oncomponents and subsystems most relevant to the supporting text in thisspecification. Planar rotary stage 130 is fully rotatable through 360degrees in a horizontal plane parallel to lower wall 120 about rotarystage rotation axis 131 and may be raised and lowered by means ofbellows feed-through 190. The use of bellows feed-through 190 allowschamber 100 to retain its aseptic condition during the motion of rotarystage 130. A suitable engine and gearing system 320 may be housed withinchamber 300. Engines, for example stepper motors, as well as gearingsystems suitable for rotating rotary stage 130 with suitable angularprecision and repeatability are well known in the art and are notfurther discussed in this specification.

As shown in FIG. 1C, at least three fiducial locating openings 132, 134,and 136 are provided in rotary stage 130. Fiducial locating opening 132is employed for receiving container tubs 530 holding sterilizedpharmaceutical containers 510 pre-packed in a predetermined pattern incontainer nests 500. The container tubs 530 are typically substantiallyrectangular and are sealed with peelable covers 520. Suppliers ofpharmaceutical containers provide their product in this format to usersof the apparatus of the present specification. Fiducial locating opening134 is employed for receiving container closure tubs 630 holdingsterilized pharmaceutical containers closures 610 pre-packed in apredetermined pattern in container closure nests 600. The containerclosure tubs 630 are typically substantially rectangular and are sealedwith peelable tub covers not shown in FIG. 1A to FIG. 1G. The peelablecovers of tubs 630 are functionally identical to peelable covers 520.Suppliers of pharmaceutical containers provide their product in thisformat to users of the apparatus of the present specification. In theinterest of the compactness of system 1000, the rectangular axes oflocating openings 132, 134, and 136 may be oriented at an angle withrespect to the radial direction of the rotary stage 130 in order toensure a suitably small radius for rotary stage 130.

Suitable container nests 500 and container closure nests 600; containertubs 530 and container closure tubs 630; and peelable tub covers 520 aredescribed in co-pending U.S. patent application Ser. No. 14/912,145, thespecification of which is hereby incorporated in full. Alternative covergripping arrangements for the removal of tub covers from tubs are alsodescribed in co-pending U.S. patent application Ser. No. 14/398,538, thespecification of which is hereby incorporated in full.

In the interest of clarity, FIG. 1A to FIG. 1G show, and the associatedtext to follow below will describe, the use of a single tub 530 ofpharmaceutical containers 510 along with a single tub 630 of containerclosures 610. In practice, container closures 610 are provided asmultiple nests 600 per container closure tub 630. To this end rotarystage 130 may contain more than one fiducial locating opening 132 toeach receive a container tub 530 holding sterilized pharmaceuticalcontainers 510 pre-packed in one container nest 500. In yet otherimplementations, more than one nest 500 of containers 510 may be presentin a single pharmaceutical container tub 530.

Fiducial locating opening 136 is specifically arranged to receivecontainer nests 500 bearing pharmaceutical containers 510. Whereas tubs530 and 630 naturally locate in fiducial locating openings 132 and 134and are suspended by their own rims once in opening 132 and 134,containers 510 are correctly located in opening 136 and retained inposition by some other means. To this end, fiducial locating opening 136comprises four fiducial retaining guides 137. Baseplate 138 is locatedwithin fiducial locating opening 136 as a loose component of system1000, and rests on the horizontal portions at the bottoms of each of thefour fiducial retaining guides 137 (see FIG. 1C and FIG. 1D). Thisarrangement allows baseplate 138 to move freely, guided by the fiducialretaining guides 137. We shall return to this arrangement whendiscussing the closing of containers with container closures.

FIG. 1E shows fiducial locating opening 136 as empty, while a cover 520is being peeled from container tub 530 in fiducial locating opening 132(not visible) to expose nest 500 bearing pharmaceutical containers 510.At this point in the operation of system 1000, a cover similar to cover520 has already been pealed from tub 630 in fiducial locating opening134 (not visible) to expose nest 600 bearing container closures 610.FIG. 1G shows a close-up detailed view of the peeling of cover 520.Cover removal station 140 is rotatable about cover removal stationrotation axis 144 parallel to rotary stage rotation axis 131 andcomprises an engagement tool 142, which, in this particular embodiment,is fork-shaped in order to engage with a cover removal fixture 540attached to cover 520. Cover removal fixture 540 is pre-attached tocover 520 before tub 530 is transferred into system 1000 via door 102(See FIG. 1A). In the embodiment shown in FIG. 1E and FIG. 1G, coverremoval fixture 540 is clipped to cover 520 and has a ball-shapedappendage to allow it to be engaged by engagement tool 142. Othercombinations of cover removal fixtures and engagement tools arecontemplated and system 1000 is not limited to the particularcombination of cover removal fixture and engagement tool shown in FIG.1A, FIG. 1E and FIG. 1G. Cover removal fixture 540, for example, may bemanufactured as an integral or even monolithic part of cover 520 for usein filling systems such as filling system 1000. Or it may be clipped tocover 520 during the placement into tub 530 of nests 500 bearingcontainers 530 and during the placement into tub 630 of nests 600bearing container closures 610.

Rotary stage 130 may be lowered to assist in obtaining a less acuteangle between cover 520 and tub 530. Too acute an angle can lead to thetearing of cover 520. Cover removal station 140 can be rotated whilerotary stage 130 rotates so that the combined motions of cover removalstation 140 and rotary stage 130 provide a low stress path for theremoval of cover 520, thereby limiting the chances of tearing of cover520. In particular, cover removal station 140 may be rotated to ensurethat engagement tool 142 is not present above fiducial locating opening132 when container tub 530 is placed in or removed from fiduciallocating opening 132.

In some embodiments, system 1000 comprises a single cover removalstation 140 for sequentially removing covers from tubs 520 and 620. Inother embodiments, system 1000 may be equipped with two or more coverremoval stations 140 for dedicated removal of covers from tubs 520 and620 and other additional tubs. In some embodiments covers aresimultaneously removed from tubs 520 and 620 and from other tubs, allthe removal processes benefiting from a single rotary motion of rotarystage 130.

In FIG. 1A, FIG. 1B, and FIG. 1F a filling station 170 for fillingpharmaceutical containers 510 with pharmaceutical fluid productcomprises pharmaceutical fluid product feed line 172 supplyingpharmaceutical fluid product to a pharmaceutical fluid product dispenserhead 174 (See FIG. 1F). Filling station 170 is rotatable about fillingstation rotation axis 176 parallel to rotary stage rotation axis 131.Filling station 170 and rotary stage 130 can simultaneously orsequentially rotate to place dispenser head 174 over an opening of anyselected container 510 in nest 500 when nest 500 is seated in fiduciallocating opening 136. This allows every container 510 in nest 500 to befilled with pharmaceutical fluid product by product dispenser head 174.When not engaged in filling containers 510, filling station 170 may berotated to swing dispenser head 174 completely away from fiduciallocating opening 136, thereby allowing nests 600 bearing containerclosures 610 to be placed on top of nest 500 with a closure 610 directlyon top of an opening of every container 510 residing in fiduciallocating opening 136.

Another term employed to describe dispenser head 174 is “fillingneedle”. Suitable filling needles and protective sheathing arrangementsfor such filling needles are described in co-pending U.S. patentapplication Ser. Nos. 14/890,223 and 15/199,771, the specifications ofwhich are hereby incorporated in full.

FIG. 1A and FIG. 1B show two vacuum pickup systems 150 and 160, eachrespectively comprising a plurality of suction cups 152 and 162 (SeeFIG. 1B). Vacuum pickup system 150 is arranged to pick up nests 500 ofcontainers 510 by means of suction cups 152, and vacuum pickup system160 is arranged to pick up nests 600 of containers 610 by means ofsuction cups 162. Vacuum pickup system 160 may be raised and lowered inorder to allow suction cups 162 to engage with different nests 600 ofcontainer closures 610 contained at differing depths inside tub 630. Tothis end, vacuum pickup system 160 may comprise a bellows feed-throughallowing vertical motion whilst maintaining the aseptic integrity ofchamber 100. Suitable vacuum pumps, or vacuum lines from a vacuum sourceexternal to system 1000, may be connected to vacuum pickup systems 150and 160, and ensure suitable vacuum at the suction cups 152 and 162.

Cameras 210 and 220 are disposed to view and record the positioning ofsuction cups 152 and 162 on nests 500 and 600 respectively. In theembodiment shown in FIG. 1A, cameras 210 and 220 are disposed withinchamber 200 and view nests 500 and 600 through sealed windows 112 and122 respectively. In other embodiments, cameras 210 and 220 may bedisposed within chamber 100 and view nests directly from within chamber100.

Container closing ram system 180, shown in FIG. 1A, FIG. 1B, and FIG.1D, comprises upper ram plate 182 disposed within chamber 100 aboverotary stage 130, lower ram plate 184 disposed within chamber 100 belowrotary stage 130, and ram drive 310 within chamber 300. Ram drive 310 isdisposed for driving lower ram plate 184 vertically toward upper ramplate 182 via bellows feed-through 186. Loose base plate 138 of fiduciallocating opening 136, when located above lower ram plate 184 by suitablyrotating rotary stage 130, is pushed upward by ram plate 184 and isguided in the process by the fiducial retaining guides 137 (See FIG.1D). When the closures 610 in closure nest 600 are ultimately pushedagainst upper ram plate 182, they are forced into the openings of thecontainers 510 in nest 500. This creates a sandwiched nest of closedcontainers 510, each closed by a corresponding closure 610. As shown inFIG. 1D, nests 500 and 600 are forced together in the process to createa compound nest 500/600.

Controller 400, shown in FIG. 1A and FIG. 1B, may communicate with therest of system 1000 via control communications line 410, or may becontained physically within system 1000, for example, within chamber200. Controller 400 may have suitable memory and a processor containsuitable software programming instructions which, when loaded in thememory executed by the processor, control the motions of ram system 180,vertical motion and rotating action of rotary stage 130, the applicationof vacuum to vacuum pickup systems 150 and 160, the imaging by cameras210 and 220, the vertical motion of vacuum pickup system 160, anyrotational or vertical motions required from cover removal stations 140and filling station 170, as well as the on-and-off valving of thepharmaceutical fluid product supply to dispenser head 174. Suitablevalves and pumps, typically peristaltic pumps, required for thepharmaceutical fluid product supply to dispenser head 174 are well knownin the art and may be housed in chamber 200 or may be located outsidesystem 1000. The various mechanical drives for the subsystems describedabove are well-known in the art, will not be discussed here in detail.These may typically be housed in chamber 200 of system 1000. Thesoftware, when executed by the processor, instructs the rotary stage torotate to angular positions that are either predetermined or based onimage information from the cameras and controls the cover removalstations, the filling station, the vacuum pickup systems, and the ramsystem to operate specifically in conjunction with the rotary stage.

A method based on system 1000 for filling nested pharmaceuticalcontainers with a pharmaceutical fluid product will now be described atthe hand of the flow chart given in FIG. 2A, and which is continued inFIG. 2B.

The phrase “iterative and serial”is employed in this specification to describe the fact that the sameoperational steps are repeatedly used to fill the various containers andthe fact that the containers are filled one after another, as opposed tosimultaneously. In some embodiments multiple containers may besimultaneously filled using a filling station with multiple dispenserheads.

Steps [2040], [2050], and [2060] each involves rotating the rotary stage130 and operating another device, being respectively the cover removalstation 140, one of the at least one vacuum pickup systems (for example150 and/or 160), and the filling station 170.

In the embodiment described at the hand of FIGS. 1A to 1F, each of steps[2040], [2050], [2060], [2070], and [2080] comprises rotating a rotarystage, for example rotary stage 130, bearing the container nests andcontainer closure nests.

In other embodiments a plurality of the steps of removing a containertub cover from at least one container tub 530; removing a container tubcover from at least one container closure tub 630; transferring to thedestination fiducial locating opening 136 the container nest 500;dispensing a pharmaceutical fluid substance into pharmaceuticalcontainers 510; transferring to the destination fiducial locatingopening 136 one of the at least one container closure nests 600; andpositioning the aligned container nest 500 and closure nest 600 in theramming system 180 comprises rotating a rotary stage bearing thecontainer nests and container closure nests.

In a general embodiment, at least one of the steps of removing acontainer tub cover from at least one container tub 530; removing acontainer tub cover from at least one container closure tub 630;transferring to the destination fiducial locating opening 136 thecontainer nest 500; dispensing a pharmaceutical fluid substance intopharmaceutical containers 510; transferring to the destination fiduciallocating opening 136 one of the at least one container closure nests600; and positioning the aligned container nest 500 and closure nest 600in the ramming system 180 comprises rotating a rotary stage bearing thecontainer nests and container closure nests.

It is to be noted that neither filling system 1000, nor the associatedmethod, needs to employ the vibratory bowls or escapements that aretypical of the prior art. Unlike many prior art systems, filling system1000 also does not require the use of gloves for use by the operator toaccess the interior of the chamber.

The system above has been described as employing a controller that runsstored software running on a general-purpose computer platform, but itcould also be implemented in whole or in part using special-purposehardware.

The system described above also employs fiducial openings defined in therotary stage to hold the tubs and nests, but it could also employ othertypes of fiducial structures that include other configurations ofconstraining surfaces sufficient to hold the tubs and nests in place.Notched posts mounted on the rotary stage could hold the tubs and/ornests above the rotary stage, for example.

Another embodiment of a filling system according to the invention may bein all respects identical to the embodiments described above at the handof FIGS. 1A and 1B, with the exception of the vacuum pickup system(s)150 or 160. FIGS. 3A and 3B show a portion of a filling system asdescribed above. FIG. 3B, in particular, focuses on the general area ofone of the vacuum pickup systems, by way of example, vacuum pickupsystem 150. In this alternative embodiment, vacuum pickup system 150 isreplaced by reconfigurable vacuum pickup system 150′. Vacuum pickupsystem 160 of FIGS. 1A and 1B may similarly be replaced by areconfigurable vacuum pickup system 160′ of the same arrangement asvacuum pickup system 150′. In the interest of clarity, vacuum pickupsystem 160′ is not shown in FIG. 3A or 3B. In other embodiments, asingle reconfigurable vacuum pickup system 150′ may be employed to pickup both container nests and container closure nests. Vacuum pickupsystem 150′ may access the container nests and container closure nestsby rotation of rotary stage 130.

Vacuum pickup system 150′ comprises two rotary arms 154 a′ and 154 b′,in their turn respectively comprising pluralities of suction cups 152 a′and 152 b′. Vacuum pickup system 150′ is arranged to pick up nests 500of containers 510 by means of suction cups 152 a′ and 152 b′. Vacuumpickup system 150′ may also be arranged to pick up nests 600 ofcontainer closures 610 by means of suction cups 152 a′ and 152 b′. Aswith vacuum pickup system 150, vacuum pickup system 150′ may be raisedand lowered in order to allow suction cups 152 a′ and 152 b′ to engagewith different nests 600 of container closures 610 contained atdiffering depths inside tub 630.

Suction cups 152 a′ and 152 b′ are arranged on rotary arms 154 a′ and154 b′ as pluralities of sets of linearly arranged suction cups 152 a′and 152 b′, each set of linearly arranged suction cups 152 a′ and 152 b′being arranged at a different angle perpendicular to the longitudinalaxes of rotary arms 154 a′ and 154 b′. This arrangement allows rotaryarms 154 a′ and 154 b′ to be rotated about their longitudinal axes inorder to orient different sets of linearly arranged suction cups 152 a′and 152 b′ to engage with different nests 500 of containers 510. Thisallows the sets of suction cups 152 a′ and 152 b′ to be individuallyselectable for use. Rotation of rotary arms 154 a′ and 154 b′ may beperformed manually. In other embodiments, rotation of rotary arms 154 a′and 154 b′ may be by means of a suitable motorized drive incorporated invacuum pickup system 150′ and controlled by controller 400 shown in FIG.1A.

By selecting different sets of linearly arranged suction cups 152 a′ and152 b′ via the rotation of rotary arms 154 a′ and 154 b′, the sets ofsuction cups 152 a′ and 152 b′ may be disposed to engage with differentcontainer nests 500 bearing containers 510, or container closure nests600 bearing container closures 610.

FIGS. 3A and 3B show vacuum pickup system 150′ as comprising two rotaryarms, being rotary arms 154 a′ and 154 b′. In other embodiments, one ormore arms may be employed, all embodiments sharing the concept of aselectable configuration of suction cups. Whereas the selection ofsuction cup configurations in FIG. 3A and FIG. 3B is by means ofrotation of the arms 154 a′ and 154 b′ bearing the suction cups 152 a′and 152 b′, the selecting in other embodiments may be on a differentbasis of configuration, including, for example without limitation,lateral translation of suction-cup-bearing arms in a plane parallel tothe rotation plane of rotary stage 130 in order to engage different setsof suction cups with container nests or container closure nests. InFIGS. 3A and 3B suction cups are arranged in linear sets. In otherembodiments non-linear arrangements of suction cups may be employed.

Turning now to FIG. 3B specifically, we consider members 149 and 139 inmore detail. In one embodiment, reconfigurable stopping member 149 isshown as having two different ends of which a first end may be selectedfor use by suitable rotation of reconfigurable stopping member 149 aboutstopping member rotation axis 141 to a predetermined set position. Inthe set position, reconfigurable stopping member 149 provides a hardstop for a proximal end of container 530 against the selected end ofreconfigurable stopping member 149 along a direction parallel to thelongitudinal axes of rotary arms 154 a′ and 154 b′. In this embodiment,reconfigurable stopping member 149 may be rotated through 180 degrees todispose the second end of reconfigurable stopping member 149 to stopcontainer 530. The second end of reconfigurable stopping member 149 maybe configured to stop the proximal end of container 530 at a differentpoint than where the first end of reconfigurable stopping member 149stops the proximal end of container 530

Restraining member 139 is configured to push against a distal end ofcontainer 530. While different means are contemplated to ensure thepushing action of restraining member 139, one particular suitable meansis by providing restraining member 139 with suitable spring loading torotate about axis 143. By the above operation, reconfigurable stoppingmember 149 and restraining member 139 together allow container 530 to bepositioned at an exact location parallel to the longitudinal axes ofrotary arms 154 a′ and 154 b′. The particular exact location isselectable by selecting the appropriate end of reconfigurable stoppingmember 149 to stop container 530. This arrangement allows containers 530of different dimensions parallel to the longitudinal axes of rotary arms154 a′ and 154 b′ to be located at exact predetermined locations withrespect to sets of suction cups 152 a′ and 152 b′.

A particular set of suction cups 152 a′ and 152 b′ may be selected tomatch the selection of the particular end of reconfigurable stoppingmember 149. In this way, vacuum pickup system 150′ may be set to aconfiguration that ensures that a selected size of container 530 isprecisely positioned to allow container nests 500 within container 530to be engaged by specific sets of suction cups 152 a′ and 152 b′. Vacuumpickup system 150′ is thereby reconfigurable to engage with nests ofdifferent sizes within containers of different sizes.

In the interest of clarity, the description above, as well as FIGS. 3Aand 3B, show an arrangement that allows for the exact positioning ofcontainers 530 along only one dimension in the rotation plane of rotarystage 130, the dimension of the containers perpendicular to the onedimension being assumed to be identical. In such an arrangement,fiducial locating openings 132 and 134 are sized to constrain containers530 in the perpendicular dimension in the rotation plane of rotary stage130.

In another embodiment, a further reconfigurable stopping member andrestraining member may be added to the arrangement of FIG. 3A and FIG.3B in order to address the positioning of container 530 in theperpendicular direction within the rotation plane of rotary stage 130.To allow the positioning of container 530 in this perpendiculardirection, fiducial locating openings 132 and 134 are not sized toconstrain containers in any direction within the rotation plane ofrotary stage 130.

In the embodiments described above, reconfigurable stopping member 149has been described as having two ends of which one is selected for useat any one time by rotating reconfigurable stopping member 149 aboutstopping member rotation axis 141. In other embodiments, reconfigurablestopping member 149 may be shaped or configured to have more than twostopping ends, the ends being selectable by suitable rotation ofreconfigurable stopping member 149 about stopping member rotation axis141. In one embodiment, in which the reconfigurable stopping member hasa very large number of stopping ends, the reconfigurable stopping membermay assume the shape of a cam, representing a large plurality ofpossible stopping ends that may be selected via rotation of thereconfigurable stopping member about a suitable stopping member rotationaxis.

In general, the system described at the hand of FIGS. 3A and 3Bcomprises a reconfigurable fiducial nest positioning system. Thereconfigurable fiducial nest positioning system comprises a movableplatform comprising fiducial locating opening 132, reconfigurablestopping member 149, and restraining member 139. In the case of thesystem of FIGS. 3A and 3B, the movable platform is rotary stage 130. Asexplained later, other movable platforms are also contemplated. To theextent that, for example, tub 530 positionally constrains and locatesnest 500 inside tub 530, any system that fiducially locates tub 530inherently also fiducially locates nest 500.

The various embodiments contemplated all comprise a reconfigurablevacuum pickup system that may be configured to engage its suction cupswith corresponding areas on a pharmaceutical container nest. Thecontainers in the container nest may be closed by correspondingcontainer closures suspended in a container closure nest. The planarsurface of the container closure nest may have an outline that leavespass-throughs on its perimeter for the suction cups to pass through toengage with the container nest. By way of example, in FIG. 3apass-throughs 602 are shown on the perimeter of closure nest 600.Alternatively or additionally, the container closure nest may havesuitable openings in its planar interior to serve as pass-throughs forthe suction cups to pass through to engage with the container nest. Thevacuum pickup systems contemplated are further configured and disposedto pick up the combination of nested containers and their closures bythe container nest, as opposed to by the closure nest.

In a general embodiment, a nest handling subsystem comprises areconfigurable vacuum pickup system for picking up container nestsand/or container closure nests may comprise one or more arms bearing aplurality of sets of suction cups. By reconfiguration of the vacuumpickup system a set of suction cups may be selected from among theplurality of sets of suction cups, the selected set of suction cupsbeing pre-arranged to engage with a particular container nest orcontainer closure nest. The selection may be on the basis of one or bothof the size and the shape of the nest. The nest handling system mayfurther comprise at least one pair of a reconfigurable stopping member149 and a restraining member 139 disposed proximate opposing ends of afiducial locating opening 132 for holding a tub 530 containing containernests 500 bearing containers 510 in order to engage with opposing endsof the tub 530. The stopping and restraining members are disposed toposition tub 530 in a predetermined position that ensures that theselected set of suction cups can engage with the container nests and/orcontainer closure nests.

As is the case with opening 132, opening 134 of FIG. 3A may also beserved by at least one set of a reconfigurable stopping member, beingmember 145 in this case, and a restraining member, being member 135 inthis case. Reconfigurable stopping member 145 and a restraining member135 function with respect any tub in opening 134 in the same way asreconfigurable stopping member 149 and a restraining member 139 functionwith respect any tub in opening 132.

The various embodiments above have been described in terms of FIG. 1A toE and FIG. 3A, and FIG. 3B in which the vacuum pickup system 150, 160 isdescribed as part of a pharmaceutical filling system 1000. However,vacuum pickup system 150′, 160′ may also be employed in its own rightother apparatus not limited to the filling system of FIG. 1A to 1E, or,in fact, to filling systems in general. Some other example applicationsinclude, without limitation, lyophilizing systems. It may be applied tosuitable nests of any objects arranged in a predetermined pattern.Furthermore, while the system 1000 of FIG. 1A to FIG. 1E employs arotary stage 130, the reconfigurable vacuum pickup system 150′ mayemploy any suitable movable platform comprising suitable fiduciallocating openings.

The method described above at the hand of FIGS. 2A and 2B may now alsobe described in more detail with reference to FIG. 3A and FIG. 3B. Theproviding at least one vacuum pickup system as part of the providing afilling apparatus step [2010] may comprise providing at least onereconfigurable vacuum pickup system 150′, the at least onereconfigurable vacuum pickup system 150′ comprising a plurality of setsof suction cups 152 a′ and 152 b′.

The providing a filling apparatus step [2010] may comprise providing arotary stage 130 with a destination fiducial locating opening 136 and atleast two source fiducial locating openings 132, 134, each sourcefiducial opening having at least one pair of a reconfigurable stoppingmember 149 and a restraining member 139.

The method may further comprise operating [2095] the at least one vacuumpickup system 150′, 160′ with the first predetermined set of suctioncups selected to engage with the container nest 500 and jointly removethe container nest 500 and container closure nest 600 from the rammingsystem 180.

We have considered in FIG. 3A and FIG. 3B alternative embodiments of thearrangements of vacuum pickup systems 150 and 160 of FIG. 1a in the formof vacuum pickup systems 150′ and 160′; and the positioning arrangementsassociated with source openings 132 and 134 in the form of elements135,145,139, and 149. We now turn our attention to alternativeembodiments for the arrangements around destination opening 136 of FIG.1A and FIG. 3A. FIG. 4A and its close up view in FIG. 4B show the systemof FIG. 3A with a different embodiment of the arrangement arounddestination opening 136. While cameras 210 and 220 of FIG. 1A may beemployed in conjunction with controller 400 and rotation of rotary stage130 to position nest 500 at opening 136, and to position nest 600 overnest 500 at opening 136, the adjustable destination fiducial positioningsystem of FIG. 4A and FIG. 4B comprising rotary positioning elements 164a and 164 b may be alternatively or additionally employed to accuratelyposition nests 600 and 500.

Typical industrial container nests are not manufactured to a dimensionalstandard, and, as a result, any system for filling and closing nestedcontainers 510 has to have a means to accurately position differentlysized nests 500 bearing the containers 510. To this end, rotarypositioning elements 164 a and 164 b may have different sets of pairedpositioning surfaces 167 a,167 b and 163 a,163 b allowing nests 500 ofspecific dimensions to be accurately fitted between such pairedpositioning surfaces. In FIG. 4B, nest 500 fits such that its twoopposing ends in a first dimension touch mutually facing surfaces 167 aand 167 b of rotary positioning elements 164 a and 164 b respectively.By mutually counter-rotating elements 164 a and 164 b about respectivelyaxes 166 a and 166 b, surfaces 167 a and 167 b may be made to face eachother and may thereby allow the precise positioning between them of anest of different length in the first dimension.

As is evident from FIG. 4B, when surfaces 167 a and 167 b face eachother, the nest positioned snugly between them may be retained in aprecise and predetermined vertical position by resting on surfaces 165 aand 165 b of rotary positioning elements 164 a and 164 b respectively.When surfaces 163 a and 163 b face each other, the alternative nestpositioned snugly between them may retained in a precise andpredetermined vertical position by resting on surfaces 161 a and 161 bof rotary positioning elements 164 a and 164 b respectively. Elements164 a and 164 b may be rotated manually about axes 166 a and 166 brespectively. In some embodiments, the rotation of elements 164 a and164 b may be done automatically by means of motorized drives controlledby controller 400 and suitable control software. That control may bebased on predetermined dimensional data relating to the nest beingpositioned between the surfaces of elements 164 a and 164 b. It may alsobe based on input data derived from imaging data obtained from cameras210 and/or 220. Further, the rotation may take place as the nest 500 islowered into position so that the particular surfaces of elements 164 aand 164 b destined to engage with the opposing ends of the nest 500along the first dimension may serve as closing horizontal grip on nest500 as the surfaces rotate toward the position in which they face eachother. In this embodiment, the horizontal positioning and verticalpositioning of a nest between elements 164 a and 164 b are not mutuallyindependent.

Another arrangement as shown in FIG. 4A and FIG. 4B for the firstdimension of the nest 500, may also be established for the second planardimension of nest 500 perpendicular to the first dimension. This allowsany nest 500 placed at opening 136 to be accurately located in alocation predetermined by the choice of setting of rotary positioningelements 164 a and 164 b.

Another embodiment of rotary positioning elements is shown in FIG. 5Aand FIG. 5B. In contrast with the embodiment of FIG. 4A and FIG. 4Bdescribed immediately above, the horizontal positioning and verticalpositioning of a nest between two mutually counter-rotatable elements164 a′ and 164 b′ in FIG. 5A and FIG. 5B are mutually independentpositioning actions. This is achieved by employing, in each of the twomutually perpendicular planar dimensions addressed in the embodimentimmediately above, a pair of fixed opposing planar tabs 165 a′ and 165b′ to position nest 500 in the vertical dimension, and a pair of rotarypositioning elements 164 a′ and 164 b′ to position nest 500 in the firsthorizontal dimension. In this embodiment, each of the elements 164 a′and 164 b′ comprises two rotatable elements ganged on axles 166 a′ and166 b′ respectively to rotate in unison and mutual alignment either sideof planar tabs 165 a′ and 165 b′ within bosses 169 a′ and 169 b′respectively. The sets of rotary elements 164 a′ and 164 b′, beyond eachbeing divided in to two ganged elements, serve to confine the nest 500in the horizontal dimension in the same fashion as rotary elements 164 aand 164 b in the embodiment of FIG. 4A and FIG. 4B described immediatelyabove.

While elements 164 a′ and 164 b′ may be designed to be of more complexshape, we show in FIG. 5A and FIG. 5B a very simple implementation inwhich surfaces 167 a′ of rotary elements 164 a′ and surfaces 167 b′ ofrotary elements 164 b′ serve to position nest 500 in the firsthorizontal dimension. By rotating elements 164 a′ joined by axle 166 a′counter-clockwise within boss 169 a′ and rotating elements 164 b′ joinedby axle 166 b′ clockwise within boss 169 b′, Surfaces 163 a′ and 163 b′may be made to face each other and thereby a nest of different length inthe first horizontal dimension may be positioned and accurately locatedbetween elements 164 a′ and 164 b′.

Ganged elements 164 a′ and 164 b′ may be rotated manually about the axesof axles 166 a′ and 166 b′ respectively inside bosses 169 a′ and 169 b′respectively. In some embodiments, the rotation of elements 164 a′ and164 b′ may be done automatically by means of motorized drives controlledby controller 400 and suitable control software. That control may bebased on predetermined dimensional data relating to the nest beingpositioned between the surfaces of elements 164 a′ and 164 b′. It mayalso be based on input data derived from imaging data obtained fromcameras 210 and/or 220. Further, the rotation may take place as the nest500 is lowered into position so that the particular surfaces of elements164 a′ and 164 b′ destined to engage with the opposing ends of the nest500 along the first dimension may serve as closing horizontal grip onnest 500 as the surfaces rotate toward the position in which they faceeach other.

FIG. 5A and FIG. 5B show a further set of paired mutuallycounter-rotatable rotary positioning elements, not numbered for the sakeof clarity, ganged similarly to rotary elements 164 a′ and 164 b′, anddisposed to accurately locate nest 500 independently in the verticaldimension and in a second planar dimension of nest 500 perpendicular tothe first dimension.
